"We're fortunate in the fact that it didn't strike any houses," Brennan said.

The McCafferty family, which owns the plane, says it's registered in Maryland, where they live, but had rented it out to a Delaware man name Wayne Gilchrist, who had intended to go flying with his friend.

"Obviously something went wrong with this airplane. It's unknown right now what it was, but typically airplanes like this will suffer from engine failure, and that results in these off-airport landings," said Arthur Wolk, aviation expert.

Wolk says the FAA will be looking at a number of factors including the plane's mechanics.

While what caused the crash remains a mystery, residents are grateful this wasn't worse.

"Thank God. By the grace of God everybody is OK because it was nothing but the grace of God with this one," said O'Neil.

The crash caused a fuel leak, which crews worked to control with foam.

All streets around the crash scene were reopened shortly before 5 p.m.

Police say the plane will be removed Thursday morning, where the FAA will begin looking into mechanical issues, and other possible causes for the crash.
